Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998404, here are decompositions:

5 + 998399 = 998404
23 + 998381 = 998404
131 + 998273 = 998404
167 + 998237 = 998404
191 + 998213 = 998404
257 + 998147 = 998404
293 + 998111 = 998404
431 + 997973 = 998404

Showing the first eight; more decompositions exist.
